Beschreibung
Zusammenfassung:	The present invention relates to an innovative thermal management system for an electric powertrain of an electric vehicle by providing heating and cooling of the different subsystems independently but using a single circuit and a single carrier fluid. Furthermore, this system can interact with the entire air conditioning system of the electric vehicle. The thermal management system, by means of a single circuit crossed by a single carrier fluid, is separately enslaved to an electric motor, an inverter, a speed reducer and a source of energy (battery, fuel cell device and similar) with appropriate adjustment devices. Advantageously, the thermal management system can operate according to multiple operating modes that implement different heating/cooling strategies. The use of the present invention, allows the performance of the electric powertrain to be optimized in terms of efficiency, duration and effectiveness of the heating.
